Project Information
While perusing some dovetailing websites a few days back I came across a particular hand tool on Rob Cosman's site, which he sells to assist with the completion of the saw kerf cut prior to chopping the waste out on half lap dovetails, such as on drawer fronts, as shown in the test piece in photo 5 above.
Below is the tool Rob sells on his site. He refers to it as a Kerf X -10.
There did not seem much to it and it could prove a useful hand tool in the future so I thought I would give it a go at making my own. It was surprisingly simple to make. I bought a small 8" back saw for £2.49. + shipping of a similar amount as the donor tool.
I only required the plate and the brass spine so the saw nuts were salvaged and set aside for another project.
I cut out the plate and brass spine with a 4" grinder as can be seen in photo 6 above. I then formed a small 1/4" tapered tenon using the grinder.
.
I had bought a box full of discarded bubinga tool handles at a woodworking show several year so ago for a couple of quid. I still had a few left. The handles had been discarded because the holes had been drilled off centre. This flaw actually suited my need as it would mean less grinding on my part to,eunsure the top of the spine was level with the ferrule on the handle. More for aesthetic than anything else.
.
It was just a case of tapping the tenon into the handle then securing it with a two part expoxy. A quick polish at the mop then I was done. Made in about 90 mins, well,worth the effort I think?
I made it to the same dimensions as the tool listed on Robs web page. Thanks Rob. The blade is 2 3/4" long x 3/4" deep, overall about 7".
I think I actually prefer the look of mine, of course I would say that.
Thanks for looking
David.
